On Monday, Arkansas Gov. Mike Beebe (D) vetoed a measure that would have required voters to show identification before voting, drawing renewed attention to an issue Democrats and Republicans have tussled over in numerous states.
Thanks to a handy map from the National Conference of State Legislatures, you can take a look the voter identification laws in all 50 states. Some have no regulations, while others have considerably stricter laws on the books. Click on the map for more details on the specific regulations in each state. (The data on the NCSL Web site was updated on March 7.)
* In Virginia, Gov. Bob McDonnell (R) signed a bill that would require voters to present a photo ID when they cast a ballot as soon as fall 2014. That is not reflected in the above map.
* In the key swing state of Pennsylvania, expect to hear more about the battle over voter ID laws later this year. Before the election last fall, a judge put on hold a law that would have required voters to show photo identification. The fate of the measure will be decided in a trial that is set to kick off on July 15. The law will not apply to Pennsylvania's May primaries.
